Solar cell and method for producing solar cell

A solar cell capable of preventing short-circuiting during signaling connection and a method for manufacturing the solar cell. A solar cell includes a semiconductor substrate, a first semiconductor layer having a conductivity type different from that of the semiconductor substrate. The first semiconductor layer includes a main functional portion which has a first base end portion on one side in a first direction of the semiconductor substrate over an entire length in a second direction and a plurality of first collecting portions extending from the first base end portion toward the other side in the first direction and on which a first electrode pattern is stacked, and an isolation portion which is formed linearly at an end portion on the other side in the first direction of the semiconductor substrate over an entire length in the second direction and on which the first electrode pattern is not stacked.

Solar cell and manufacturing method

A solar battery module having high photoelectric conversion efficiency and superior aesthetic appearance. A solar battery module comprises a plate-shaped front-surface protection material having, on an exterior peripheral part, a light-blocking region that blocks light; a plurality of solar battery strings each having a plurality of solar battery cells that are aligned in one line in a first direction and connected, the plurality of solar battery strings being positioned aligned in a second direction that intersects with the first direction on the back side of the front-surface protection material; a plate-shaped or sheet-shaped back-surface protection material positioned on the back side of the plurality of solar battery strings; and a sealing material filled between the front-surface protection material and the back-surface protection material. The solar battery strings are arranged so that a portion of at least one end of the solar battery cells overlaps with the light-blocking region.

Solar cell module

A transparent electrode film includes a transparent electrode disposed on a transparent film base, wherein the transparent electrode contains a transparent conductive layer and a conductive metal pattern layer. The conductive metal pattern layer is patterned in the in-plane direction of the transparent film base. The transparent conductive layer and a protecting layer are disposed in a region where the conductive metal pattern layer is provided, and the conductive metal pattern layer is disposed closer to the transparent film base than the transparent conductive layer and the protecting layer. The protecting layer includes at least one selected from the group consisting of a precious metal and a metal oxide. The transparent electroconductive layer is also disposed at opening sections where the electroconductive metal pattern layer is absent.
